Earthquake engineering

Earthquake engineering:

Earthquake engineering is treating its subject structures like defensive fortifications in military engineering but for the warfare on earthquakes. Both earthquake and military general design principles are similar: be ready to slow down or mitigate the advance of a possible attacker.

The main objectives of earthquake engineering are:

• Understand interaction of structures with the shaky ground.

• Foresee the consequences of possible earthquakes.

• Design, construct and maintain structures to perform at earthquake exposure up to the expectations and in compliance with building codes.

Earthquake engineering structure does not, necessarily, means extremely strong and expensive structure like, e.g., El Castillo pyramid at Chichen Itza shown above.

Now, the most powerful and budgetary tool of the earthquake engineering is base isolation which pertains to the passive structural vibration control technologies.
